Quality Park Reveal-N-Seal #9 Double Window Envelopes are designed for mailing invoices, statements, and QuickBooks documents without the need for labels or moistening. The two-window design keeps both the recipient and return address visible through pre-positioned windows, eliminating manual addressing. A blue security tint shields sensitive document contents from view during transit.

The self-sealing Reveal-N-Seal closure provides a strong, permanent bond without licking. A tamper-evident strip along the flap shows visible signs if the envelope has been opened, providing additional security for sensitive correspondence. Envelopes are constructed with side-seam construction from 24 lb white wove paper.
